First and foremost, we don't recommend trying this at home. Or anywhere else.
And if you have a real fear of heights, this might mess with your head. And your stomach - especially if you stare at them long enough.
These photos are from a South Korean artist named Ahn Jun, pretty much hanging out high above the streets of Seoul, Hong Kong and New York City - from the tallest buildings she could find.
And we do mean hanging - with her feet over the edge of a skyscraper or half her body out hanging out a window.
Oh and just for good measure, throw in a running on the ledge shot and a balancing on the window ledge snap.
Ahn Jun takes hundreds of photos using self-timers, then picks the best ones where she "looks peaceful or aggressive, not fearful".
Sometimes, she wears a harness but says the pictures are 100% authentic.
"People always ask whether the images are real and in all these pictures I was actually there, not photoshopped," she told the British paper The Mirror. "Of course, it is not a safe situation. But I always try to be careful."
"I have never been brave. It is a matter of overcoming the fear."
She started taking these shots four years ago and has climbed 14 skyscrapers in all - without anyone below really noticing.
"I only saw people notice me on two occasions," she said.
"The first time, a lady was just staring up at me. The second time, a family who were having BBQ party at the rooftop of the building beside my window saw me."
Update: Commenter Michael R. Barrick pointed out some similar photographs taken about ten years ago in Beijing by artist Li Wei.
Here's one of those shots - it's called '29 Levels of Freedom' and it's from 2003.
